Introduction

This is a GUI tool to estimate error propagation. It is a Tauri app written mainly in React-typescript, Python and Nim with minimal Rust.

Install

Easy way

Just install compiled packages.

Loading takes too much time (like 10 seconds). I want to use system Python instead of WASM/Pyodide

Python installation with sympy should be enough. Note that libpython should be available too.

pip install sympy

App should load system Python if you switch to system Python in Settings (may require restart depending on your system at the time this app was launched).

I want to use system LaTeX

PDF export defaults to system in every case. Remote rendering may not be avail all the time. Install XeTeX and with amsmath packages according to your OS. XeLaTeX should be available in your Path.

Copy the selected equation as an image to a clipboard

Works only in Linux or in a system that supports wl-clipboard or xclip with minor code changes. If you use Wayland install wl-copy provided by wl-clipboard or in case of X11 install xclip.

I have problems

Launch this app using commandline. It may tell something important.

I want to suffer and compile everything

OK. You'll need to clone this repository. You'll also need npm https://nodejs.org/en/, rust https://www.rust-lang.org/tools/install and nim https://nim-lang.org/.

Install npm and run in this project's root

npm i

Nim's Nimble package manager

nimble install https://github.com/jiiihpeeh/pixie supersnappy jsony nimpy ws

Note that this app utilizes a modified pixie version.

Compile callnim.nim in src-tauri

nim c -d:release --app:staticLib --gc:boehm  --noMain -d:ssl callnim.nim

Run it in development mode

npm run tauri dev

In order to update changes in compiled nim code you should make something like insignificant whitespace changes to main.rs during your programming session and save that file.

You should be ready to compile this app

npm run tauri build

Congrats?
